SPECIFICATION forming part of Letters, Patent No. 781,526, dated January31, 1905,

Application flied May la, 19o/1.* seriai No. 207,741.

To all whom t may con/cern.-

Beit known that we, THOMAS H. IvEY and JOHN GEORGE BECK, citizens of theUnited States, residing in Philadelphia, Pennsylvania, have inventedcertain Improvements in Non- Refillable-Bottle Stoppers, of which thefollowing is a specification.

One object of our invention is to provide a device for preventing therelillingof a bottle with liquid after it has once been emptied whichshall be of simpler and less expensive cmstruction than similar devicesof the same c ass.

More particularly the object of o ur invention is to improve, simplify,and cheapen the construction of the device for which Letters Patent No.687,236 were granted to us on November 26, 1901.

l invention.

t cated at a.)

In the above drawings,A illustrates` a portion of a bottlerwhose mainportion'is of the ordinary construction, but whose neck is provided withan internal annular recess, (indi- In the lowermost portion of said neckwe retain a bushing, preferably of por- -celain or glass, by means of. awasher or packing ,which is compressed betweensaid bushing and theinside of the neck. There is preferably a ange 62 on the bushing Z) forthe purpose of engaging the washer and there is within said bushing atubular guideway b3, held by means of webs b'so as to be concentric withthe flange, and consequently with the neck of the bottle. y

A valve B, whichv also serves the purpose of a float, is normally heldseated upon the upper end of the bushing by means of a the bushing o.

weight b, preferably in the form of a ball, attached to itby means of aflexible connection o6. In order that the valve B shall be v properlyguided to its seat, we provide a tubularl stem 57, fixed concentricallywithin it and designedto enter the tubular guideway b3 of In order tolessen the friction betweenthis spindle and the sides of the guide- Way,We form this latter of a corrugated or ribbed section, as indicated inFig. 4, so that there will be but a minimum bearing-surface between itand the spindle. The flexible connection b preferably passes through thespindle, which is countersunk in the valve and slightly enlarged orheaded, so as to be permanently retained in position. If a silk cord,for example, be employed as the exible connection, thiswill be knottedor cemented at its upper end and the head of the spindle 57 will becovered by a plug Zus of the same material as that of the valve,usuallycork.

In order to prevent the valve being tampered with, we provide a moldedpiece C, of

porcelain or glass, which may be described as l a tubular bushingprovided lwith a coveringhood c, supported a short distance above itsvend by means of lugs c.

.ing material, such kas cork, is fitted onto the lower end ofthe bushingC, so as to prevent the passage of liquid Ato the Vspring c2, as well asto hold said bushing tightly in place. f This ring c2 is preferablyformed of a wire of spring material formed in Va number of corrugationsand bent into circular form.

Under ordinary'conditions the valve B remains seated on the upper end ofthe bushing b, and when the bottle is inclined, as shown in Fig. 2, itis permitted to move away from said The said bushing C seat to a limitedextent to permit the outflow of liquid from the bottle. The flexibleconnection L is made of such a length, however, that the weight 65 bycatching upon the inner end of the bushing holds the valve 'from movingmore than about one-quarter 'of an inch away from its seat. rlhis,however, is amply suiiicient to permit liquid to freely flow out of thebottle. It' it beattempted to refill the bottle, the entrance of theliquid into the neck of the same will, if the neck end of the bottle beinclined below the horizontal, float the valve B to its seat-upon theend of the bushing b. In all other positions the weight L will forciblyhold the valve to its seat.

Owing to the small friction between the spindle 57 and the tubular guide3 of the bushing Z), the valve B is free to rise with the rise of liquidand be firmly seated upon the end of the bushing Z), so as to preventthe entrance of liquid into the bottle.

We claim as our invention- 1. The combination with a bottle ot' abushing held in the neck of the same, a centrallysu pported guideway insaid bushing, a valve constructed to seat on the bushing and having astein operative in said guideway, with a weight normally tending to keepthe valve seated and a flexible connection between the valve-stem andthe weight, substantially as described.

2. The combination with a bottle having a valve-seat in its neck, of avalve constructed to engage said seat, a tubular spindle attached to thevalve, a guideway for said spindle, a flexible connection extendingthrough thel spindle and a weight attached to said connection,substantially as described.

3. The combination with a bottle having a valve-seat and a guideway inits neck, of a valve of material capable olE floating, placed to engagesaid seat, a tubular spindle lixed to said valve and engaging theguideway, a weight, and a flexible connection passing through thespindle and connecting the weight and the valve. substantially asdescribed.

4. The combination with a bottle, of a Hanged bushing in the neckthereof, a washer between said bushing and the neck, a substantiallycylindrical float-valve having a tubular spindle attached to it, atubular guidewayin the bushing for said spindle, a \\'eight, and aexibleconnection passing through the spindle and attached to the valve andsaid weight, substantially as described.

5. rlhe combination with a bottle having in its neck a valve-seat and aribbed guidewagg', a l'loatable valve for said seat having a spindleoperative in said guideway, with a weight and a flexible connectionbetween the valve and said weight, substantially as described.

ln testimony whereof we have signed our names to this specification inthe presence ol two subscribing witnesses.
